SYSTEM FOR LOCKING A COUPLING OF ELEMENTS, HAVING MALE AND FEMALE ENDS

摘要

This locking system includes a male cylindrical end and a female tubular cylindrical end inside of which the male cylindrical end is to be inserted for coupling. A locking groove is hollowed in the outer surface of the male cylindrical end. The female tubular cylindrical end is bored on the side with a through-opening inside of which is arranged a mobile locking element which protrudes inside the female tubular cylindrical end in the locking groove of the male cylindrical end. A locking ring is mounted to rotate freely on the outer surface of the female tubular cylindrical end opposite the through-opening this ring having an inner surface wherein a recess having an ortho-radially variable depth enables the locking/unlocking of the mobile locking element against the locking groove depending on the ring's position. The locking groove extends in the axial direction of the male cylindrical end from a free end thereof.

1. Locking system (10) comprising a male cylindrical end (12) of a first element (14) and a female tubular cylindrical end (16) of a second element (18), the male cylindrical end (12) being intended to be engaged inside the female tubular cylindrical end (16) to couple the first element (14) to the second element (18), wherein:
a locking groove (24) is hollowed in the outer surface (20) of the male cylindrical end (12), the female tubular cylindrical end (16) is bored on the side with a through-opening (28) inside of which is arranged a mobile locking element (30) able to protrude inside the female tubular cylindrical end (16) in the locking groove (24) of the male cylindrical end (12), and a locking ring (36) is mounted, free in rotation (L, U) around the female tubular cylindrical end (16), on the outer surface (38) of the female tubular cylindrical end (16) opposite the through-opening (28), this ring (36) having an inner surface (40) wherein a recess (42) having an ortho-radially variable depth enables the locking/unlocking of the mobile locking element (30) against the locking groove (24) depending on the position of the ring (36), characterized in that the locking groove (24) extends in the axial direction (z) of the male cylindrical end (12) from a free end thereof, in order to guide and angularly limit the insertion of the male cylindrical end (12) in the female tubular cylindrical end (16).
